Did you try cloning the latest? Just updated to beta.9 :)

[kukicado]

This is a common problem if you are trying to use the minified version of the router library. Try switching to the non-minified version and the problem should go away.

@chenkie: After update angular to beta 9, this error occurred
@kukicadnan: I am using non-minified version.

I ported the custom router outlet over to my own code and an upgrade to beta 9 triggered the same issue. Here's the relevant Angular 2 commit.

[kukicado]

@dieuhd - have you also updated the other libraries including rxjs and zone (as well as devDependencies). I had that issue arise during the bump to beta 9 - but after updating all dependencies to what you see in the latest commit and using the non-minified version of the router the error went away. Is there a code sample you can share?

[dieuhd]

@kukicadnan Here are my code:

• app.component.ts

import {Component, Input} from 'angular2/core';
import {RouteConfig, Router, ROUTER_DIRECTIVES, CanActivate} from 'angular2/router';
import {HTTP_PROVIDERS}    from 'angular2/http';
import {MATERIAL_DIRECTIVES} from 'ng2-material/all';
import { AuthConfig, AuthHttp } from 'angular2-jwt';

import {LoggedInRouterOutlet} from '../directives/logined-in-outlet.directive';
import {PostsComponent} from './posts.component';
import {LoginComponent} from './login.component';
import {AuthService} from '../services/auth.service';


@Component({
    selector: 'hb-blog',
    templateUrl: '/app/components/app.component.html',
    directives: [MATERIAL_DIRECTIVES, LoggedInRouterOutlet, ROUTER_DIRECTIVES, LoginComponent]
})

@RouteConfig([
    { path: '/login', name: 'Login', component: LoginComponent },
    { path: '/posts', name: 'Posts', component: PostsComponent },
    { path: '/**', redirectTo: ['Login'] }
])

export class AppComponent { 
    public isLogined: boolean = false;
    public firstLoaded: boolean = false;
    constructor(private _router: Router, private _authService: AuthService) {

    }
    get authenticated(){
        return this._authService.isLoggedIn();
    }
    get userInfo() {
    }

    logout() {
        this._authService.logout();
        this._router.navigate(["Login"]);
    }
}

Not to hijack this thread, but as an alternative, you can also apply a @CanActivate decorator to your components. In my experimental project, I've replaced the router outlet override with a tiny @Auth decorator, which wraps @CanActivate. I'm not sure which approach I prefer syntactically, but at least this new one works.

[ric-cardo]

i got it working (using beta-11) by renaming the selector from router-outlet to auth-router-outlet

[freshprinze]

@ric-cardo Working with beta-9 too. Downgraded to beta-9 because of breaking changes.

In addition to using the non-minified router, I had to use the non-minified version of Angular 2 as well, e.g. https://cdnjs.cloudflare.com/ajax/libs/angular.js/2.0.0-beta.14/angular2.js instead of angular2.{dev|min}.js.

I still get this Primary outlet is already registered. error when trying to use a child route. RC1 angular2

[vladsava87]

I managed to get it to work by using this filter in app.component and other components with internal routing:

directives: [ROUTER_DIRECTIVES.filter(direc => direc != RouterOutlet), OverwittenRouterOutlet, ...]
